I raise three puzzles concerning self-deception: (i) a conceptual paradox, (ii) a dilemma about how to understand human cognitive evolution, and (iii) a tension between the fact of self-deception and Davidson’s interpretive view. I advance solutions to the first two and lay a groundwork for addressing the third. The capacity for self-deception, I argue, is a spandrel, in Gould’s and Lewontin’s sense, of other mental traits, i.e., a structural byproduct. The irony is that the mental traits of which self-deception is (...) a spandrel/byproduct are themselves rational. (shrink)

ABSTRACT This paper offers an account of intending to self-deceive which opposes that provided by standard intentionalist accounts of self-deception. According to my account, self-deception is attained instantaneously: to intend to self-deceive that P is thereby to self-deceive that P. Relating this to the concepts of evidence, belief and self-awareness, I develop an account of self-deception which holds that self-deceivers misrepresent themselves as believing what they profess to believe. I argue that my account yields solutions to the central problems of (...) self-deception – the static problem and the dynamic problem – while remaining faithful to the phenomena of self-deception.

The essential task of the investigation of self-deception is nothing more than establishing the boundary of it, herein known as the distinction problem of self-deception. Such a boundary is necessary for distinguishing the phenomenon of self-deception from other similar phenomena, especially wishful thinking, and sheds light on the future research of other theoretical questions posed by the phenomenon. Although philosophers have reached a vague consensus on certain necessary elements involved in the phenomenon of self-deception, there is no general agreement on (...) their details, leading to a lack of canonical literature regarding the question of what makes self-deception a unique phenomenon. In this thesis, I begin by attempting to re-establish the initial definition of self-deception by illustrating the vague consensus in the current discussion of self-deception. Then, several representative views are examined to uncover the reason for their failure to capture the distinction between self-deception and other kinds of irrationality. These findings are then used to clarify what the basic structure of self-deception should be. Finally, I develop an account revealing that the distinction problem is related to the study of the necessary attitude involved in self-deception. My analysis shows that a special kind of instability inherent in the necessary attitude involved in self-deception is the key to establishing self-deception as a distinctive case of motivated irrationality.

This paper aims to offer an alternative to the existing philosophical theories of self-deception. It describes and motivates a teleofunctional theory that models self-deception on the subintentional deceptions perpetrated by non-human organisms. Existing theories of self-deception generate paradoxes, are empirically implausible, or fail to account for the distinction between self-deception and other kinds of motivated irrationality. Deception is not a uniquely human phenomenon: biologists have found that many non-human organisms deceive and are deceived. A close analysis of the pollination strategy (...) of the mirror orchid (Ophrys speculum) provides the basis for an analysis of non-human deception as subintentionally purposive. This teleofunctional analysis is then used as the basis for a theory of self-deception that accounts for its normative and purposive features without defaulting to intentionalism. The teleofunctional theory accounts for distinction between self-deception and phenomena such as wishful thinking in an empirically plausible manner. Three objections to the theory are considered and rejected. (shrink)

Alfred Mele's deflationary account of self-deception has frequently been criticised for being unable to explain the “tension” inherent in self-deception. These critics maintain that rival theories can better account for this tension, such as theories which suppose self-deceivers to have contradictory beliefs. However, there are two ways in which the tension idea has been understood. In this article, it is argued that on one such understanding, Mele's deflationism can account for this tension better than its rivals, but only if we (...) reconceptualize the self-deceiver's attitude in terms of unwarranted degrees of conviction rather than unwarranted belief. This new way of viewing the self-deceiver's attitude will be informed by observations on experimental work done on the biasing influence of desire on belief, which suggests that self-deceivers don’t manage to fully convince themselves of what they want to be true. On another way in which this tension has been understood, this account would not manage so well, since on this understanding the self-deceiver is best interpreted as knowing, but wishing to avoid, the truth. However, it is argued that we are under no obligation to account for this since it is a characteristic of a different phenomenon than self-deception, namely, escapism. (shrink)
